EHR Builder

The EHR Builder is a domain-aware tool for health IT teams, data architects, and developers who design electronic health record systems. It provides templates for core resources (Patient, Encounter, Observation) and data relationships, supports FHIR-based schema generation, value-set constraints, and privacy-aware configurations. Use cases include starting a new EHR project, migrating from legacy schemas, or integrating patient data across vendor systems.
Core logic & features: It includes a library of resource templates, a constraint-driven validation engine, and artifact pipelines. Required features include template libraries, field-level and cross-resource validations, versioned artifact generation, and artifact export in JSON Schema and OpenAPI formats. Optional/advanced features include field mapping, value-set expansion, synthetic data generation, and integration hooks to external systems.
Workflow and usage patterns: Users specify selected resources and baseline standards, choose the compliance baseline (FHIR release), configure field constraints, and generate artifacts. The tool validates dependencies, handles missing mappings, and ensures compatibility with external systems via OpenAPI contracts. It supports localization of value sets and units and can anchor data models to privacy controls like access rules and audit logging.
Differentiators & outcomes: Distinguishing factors include privacy-preserving test data, deterministic artifact generation with seed control, and governance-ready outputs that support audits. It is designed for collaboration between clinicians, data engineers, and compliance teams, enabling faster design cycles and safer interoperability.
